As far back as the mid-1990s, residents of the Childs Park neighborhood in St. Petersburg<\/a> have complained about \u201cthe smell.\u201d The odor has been described as rotten eggs or gasoline or something else just as repugnant. People who live in the predominantly Black neighborhood have had little in the way of hard data to try to pinpoint what is in the air and whether it might be a health risk.<\/h3>\n[\/vc_column_text][\/vc_column][\/vc_row][vc_row type=”full_width_content” full_screen_row_position=”middle” column_margin=”default” column_direction=”default” column_direction_tablet=”default” column_direction_phone=”default” scene_position=”center” top_padding=”32″ bottom_padding=”32″ text_color=”dark” text_align=”left” row_border_radius=”none” row_border_radius_applies=”bg” overflow=”visible” advanced_gradient_angle=”0″ overlay_strength=”0.3″ gradient_direction=”left_to_right” shape_divider_position=”bottom” bg_image_animation=”none” shape_type=”” gradient_type=”default”][vc_column column_padding=”padding-2-percent” column_padding_tablet=”inherit” column_padding_phone=”inherit” column_padding_position=”right” column_element_direction_desktop=”default” column_element_spacing=”default” desktop_text_alignment=”default” tablet_text_alignment=”default” phone_text_alignment=”default” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_backdrop_filter=”none” column_shadow=”none” column_border_radius=”none” column_link_target=”_self” column_position=”default” gradient_direction=”left_to_right” overlay_strength=”0.3″ width=”2\/3″ tablet_width_inherit=”default” animation_type=”default” bg_image_animation=”none” border_type=”simple” column_border_width=”none” column_border_style=”solid” column_padding_type=”default” gradient_type=”default”][vc_column_text]Starting in September 2022, researchers from Eckerd College and the University of South Florida began walking through the neighborhood in 30-minute intervals several times a week using hand-held sensors to try to determine what is causing the stench. After almost 6,000 measurements, they recently presented their preliminary findings at a Childs Park Neighborhood Association meeting.<\/p>\n

Among those findings: possible concern for exposure to elevated levels of hydrogen sulfide, a toxic chemical emitted from some industrial plants. It smells like rotten eggs.<\/p>\n

The team from Eckerd consisted of Alexis Vargas, a senior marine science<\/a> student from Sarasota; Hailey Thomas, a junior marine science student from Cambridge, Ohio; and the team leader, Polina Maciejczyk, Ph.D.<\/a>, professor of chemistry<\/a> at the College.[\/vc_column_text][\/vc_column][vc_column column_padding=”no-extra-padding” column_padding_tablet=”inherit” column_padding_phone=”inherit” column_padding_position=”all” top_margin_tablet=”32″ column_element_direction_desktop=”default” column_element_spacing=”default” desktop_text_alignment=”default” tablet_text_alignment=”default” phone_text_alignment=”default” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_backdrop_filter=”none” column_shadow=”none” column_border_radius=”none” column_link_target=”_self” column_position=”default” gradient_direction=”left_to_right” overlay_strength=”0.3″ width=”1\/3″ tablet_width_inherit=”default” animation_type=”default” bg_image_animation=”none” border_type=”simple” column_border_width=”none” column_border_style=”solid” column_padding_type=”default” gradient_type=”default”][image_with_animation image_url=”15638″ image_size=”full” animation_type=”entrance” animation=”Fade In” animation_easing=”default” animation_movement_type=”transform_y” hover_animation=”none” alignment=”” img_link_large=”yes” border_radius=”none” box_shadow=”none” image_loading=”skip-lazy-load” max_width=”100%” max_width_mobile=”default”][divider line_type=”No Line” custom_height=”16″][vc_column_text]Maciejczyk and students have collected almost 6,000 measurements.<\/em>[\/vc_column_text][\/vc_column][\/vc_row][vc_row type=”full_width_content” full_screen_row_position=”middle” column_margin=”default” column_direction=”default” column_direction_tablet=”default” column_direction_phone=”default” scene_position=”center” top_padding=”64″ bottom_padding=”64″ text_color=”dark” text_align=”left” row_border_radius=”none” row_border_radius_applies=”bg” overflow=”visible” advanced_gradient_angle=”0″ overlay_strength=”0.3″ gradient_direction=”left_to_right” shape_divider_position=”bottom” bg_image_animation=”none” shape_type=”” gradient_type=”default”][vc_column column_padding=”no-extra-padding” column_padding_tablet=”inherit” column_padding_phone=”inherit” column_padding_position=”right” column_element_direction_desktop=”default” column_element_spacing=”default” desktop_text_alignment=”default” tablet_text_alignment=”default” phone_text_alignment=”default” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_backdrop_filter=”none” column_shadow=”none” column_border_radius=”none” column_link_target=”_self” column_position=”default” gradient_direction=”left_to_right” overlay_strength=”0.3″ width=”1\/1″ tablet_width_inherit=”default” animation_type=”default” bg_image_animation=”none” border_type=”simple” column_border_width=”none” column_border_style=”solid” column_padding_type=”default” gradient_type=”default”][image_with_animation image_url=”15639″ image_size=”full” animation_type=”entrance” animation=”None” animation_movement_type=”transform_y” hover_animation=”none” alignment=”” img_link_large=”yes” border_radius=”none” box_shadow=”none” image_loading=”skip-lazy-load” max_width=”100%” max_width_mobile=”default”][divider line_type=”No Line” custom_height=”16″][vc_column_text]Maciejczyk walked through the neighborhood several times a week using hand-held sensors.<\/em>[\/vc_column_text][\/vc_column][\/vc_row][vc_row type=”full_width_content” full_screen_row_position=”middle” column_margin=”default” column_direction=”default” column_direction_tablet=”default” column_direction_phone=”default” scene_position=”center” top_padding=”32″ text_color=”dark” text_align=”left” row_border_radius=”none” row_border_radius_applies=”bg” overflow=”visible” advanced_gradient_angle=”0″ overlay_strength=”0.3″ gradient_direction=”left_to_right” shape_divider_position=”bottom” bg_image_animation=”none” shape_type=”” gradient_type=”default”][vc_column column_padding=”no-extra-padding” column_padding_tablet=”inherit” column_padding_phone=”inherit” column_padding_position=”right” column_element_direction_desktop=”default” column_element_spacing=”default” desktop_text_alignment=”default” tablet_text_alignment=”default” phone_text_alignment=”default” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_backdrop_filter=”none” column_shadow=”none” column_border_radius=”none” column_link_target=”_self” column_position=”default” gradient_direction=”left_to_right” overlay_strength=”0.3″ width=”1\/1″ tablet_width_inherit=”default” animation_type=”default” bg_image_animation=”none” border_type=”simple” column_border_width=”none” column_border_style=”solid” column_padding_type=”default” gradient_type=”default”][vc_column_text]The prime suspect throughout the years, Maciejczyk and others say, is an industrial corridor that runs through the neighborhood, often just across the street from homes. Among the businesses are a concrete plant, an oil recycling facility, a metal-plating company and a food processing company. All of the businesses have permits to operate.<\/p>\n

\u201cNeighbors were complaining to neighbors and nothing was getting done,\u201d Maciejczyk says. \u201cThe collection of the data started with the City, and they\u2019ve been really good about that.\u201d Residents can call city officials and report what they smell through the Smell Something, Say Something program, and several hand-held air monitors were distributed so residents can monitor and record what\u2019s in the air.<\/p>\n

But as Maciejczyk points out, this is not a case where a chemical can be easily tied to a specific location. Factors such as wind direction and time of day come into play, as do the sophistication of the sensors and other monitors used in the area. The Eckerd team used the monitoring devices that residents had received from the City. Maciejczyk says those devices help, but they don\u2019t adequately identify some harmful pollutants such as specific volatile organic compounds.[\/vc_column_text][\/vc_column][\/vc_row][vc_row type=”full_width_content” full_screen_row_position=”middle” column_margin=”default” column_direction=”default” column_direction_tablet=”default” column_direction_phone=”default” scene_position=”center” top_padding=”32″ text_color=”dark” text_align=”left” row_border_radius=”none” row_border_radius_applies=”bg” overflow=”visible” advanced_gradient_angle=”0″ overlay_strength=”0.3″ gradient_direction=”left_to_right” shape_divider_position=”bottom” bg_image_animation=”none” shape_type=”” gradient_type=”default”][vc_column column_padding=”padding-2-percent” column_padding_tablet=”inherit” column_padding_phone=”inherit” column_padding_position=”right” column_element_direction_desktop=”default” column_element_spacing=”default” desktop_text_alignment=”default” tablet_text_alignment=”default” phone_text_alignment=”default” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_backdrop_filter=”none” column_shadow=”none” column_border_radius=”none” column_link_target=”_self” column_position=”default” gradient_direction=”left_to_right” overlay_strength=”0.3″ width=”2\/3″ tablet_width_inherit=”default” animation_type=”default” bg_image_animation=”none” border_type=”simple” column_border_width=”none” column_border_style=”solid” column_padding_type=”default” gradient_type=”default”][vc_column_text]\u201cParticles in the air,\u201d Maciejczyk says, \u201care not necessarily what people smell. We wanted to monitor for volatile organic carbons and gases, to identify the levels of these chemicals, find out if there are hot spots and what is normal.\u201d<\/p>\n

Researchers also tested the air in a second neighborhood, Disston Heights, which is similar to Childs Park and is just four miles away but doesn\u2019t have an industrial corridor running through it. \u201cWe used that as our control population site,\u201d Maciejczyk says.<\/p>\n

\u201cI lost six pounds by doing this research, walking around this neighborhood,\u201d she adds. \u201cThe data is, at most, preliminary. But it does look like Disston Heights has more of an issue with sulfur dioxide, and Childs Park has more of an issue with hydrogen sulfide.<\/p>\n

\u201cThe residents understand what\u2019s happening. They want to know if there could be a health concern. But we are focusing on the data collection and looking through scientific literature [to see] what are the ambient thresholds or what might or might not be an issue. We don\u2019t have enough data yet.<\/p>\n

\u201cAnd we don\u2019t know who the bad guy is. Every industry has a permit, and the State issues the permits. And not everything is required to be reported, because the variety of chemicals out there is so massive. A lot of it gets immediately processed into the atmosphere. And what\u2019s being emitted and what\u2019s being measured down the street [are] not always the same.[\/vc_column_text][\/vc_column][vc_column column_padding=”no-extra-padding” column_padding_tablet=”inherit” column_padding_phone=”inherit” column_padding_position=”all” top_margin_tablet=”32″ column_element_direction_desktop=”default” column_element_spacing=”default” desktop_text_alignment=”default” tablet_text_alignment=”default” phone_text_alignment=”default” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_backdrop_filter=”none” column_shadow=”none” column_border_radius=”none” column_link_target=”_self” column_position=”default” gradient_direction=”left_to_right” overlay_strength=”0.3″ width=”1\/3″ tablet_width_inherit=”default” animation_type=”default” bg_image_animation=”none” border_type=”simple” column_border_width=”none” column_border_style=”solid” column_padding_type=”default” gradient_type=”default”][image_with_animation image_url=”15635″ image_size=”full” animation_type=”entrance” animation=”Fade In” animation_easing=”default” animation_movement_type=”transform_y” hover_animation=”none” alignment=”” border_radius=”none” box_shadow=”none” image_loading=”skip-lazy-load” max_width=”100%” max_width_mobile=”default”][divider line_type=”No Line” custom_height=”16″][vc_column_text]Polina Maciejczyk, Ph.D.<\/em>[\/vc_column_text][\/vc_column][\/vc_row][vc_row type=”full_width_content” full_screen_row_position=”middle” column_margin=”default” column_direction=”default” column_direction_tablet=”default” column_direction_phone=”default” scene_position=”center” top_padding=”32″ bottom_padding=”32″ text_color=”dark” text_align=”left” row_border_radius=”none” row_border_radius_applies=”bg” overflow=”visible” advanced_gradient_angle=”0″ overlay_strength=”0.3″ gradient_direction=”left_to_right” shape_divider_position=”bottom” bg_image_animation=”none” shape_type=”” gradient_type=”default”][vc_column column_padding=”padding-2-percent” column_padding_tablet=”inherit” column_padding_phone=”inherit” column_padding_position=”all” column_element_direction_desktop=”default” column_element_spacing=”default” desktop_text_alignment=”default” tablet_text_alignment=”default” phone_text_alignment=”default” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_backdrop_filter=”none” column_shadow=”none” column_border_radius=”none” column_link_target=”_self” column_position=”default” el_class=”lg_text” gradient_direction=”left_to_right” overlay_strength=”0.3″ width=”1\/1″ tablet_width_inherit=”default” animation_type=”default” bg_image_animation=”none” border_type=”simple” column_border_width=”none” column_border_style=”solid” column_padding_type=”default” gradient_type=”default”][vc_column_text]\u201cWhat you smell, is that what\u2019s being emitted?
