“…This could be as a result of generation of these heavy metals from the chemicals in the stores and possibly because heavy metals accompanying particulate matter generated outdoor were trapped inside the stores' ambient air as a result of poor ventilation. Heavy metals; cadmium, lead, arsenic, chromium and cobalt are capable of inducing oxidative stress (Marrugo et al, 2020).…”

In most developing countries, stores, where chemical substances are sold, are poorly ventilated, and best practices are not followed. This can result in the contamination of the ambient air inside the stores with toxicological implications for the lungs. This work aimed at determining the risk of pulmonary disease in chemical storekeepers in the Ariaria international market Aba by the evaluation of exhaled breath condensate (EBC) biomarkers of oxidative stress. A gas monitor was used for gas sampling while an Aerocet analyzer was used for particulate matter determinations. Exposed filter paper was used for the sampling of heavy metals in the air, and the determination was done using atomic absorption spectrophotometry. The exhaled breath condensate was collected with a refrigerated condenser, and the markers of oxidative stress were determined spectrophotometrically. Concentrations of particulate matter (PM1, PM2.5, PM4, PM7, PM10) were elevated in all the chemical stores studied. Our findings also showed that the indoor air of the chemical stores studied was polluted with SO2, NO2, NH3 and H2S, as their concentrations were respectively higher than the WHO standard values. Concentrations of all the heavy metals present in the ambient air of the chemical stores were also higher than the Nigerian Environmental Standard and Regulation Enforcement Agency (NESREA) standard values. Chemical storekeepers at the Ariaria international market exhaled increased concentrations of thiobarbituric acid reactive substances (TBARS), H2O2, and lower concentrations of glutathione (GSH). The pH values of the exhaled breath condensates were decreased and slightly acidic. It therefore means that the storekeepers were exposed to polluted ambient air inside the stores. This resulted to airway oxidative stress in the storekeepers as reported herein. Therefore, storekeepers of chemical stores in the Ariaria international market, Aba Nigeria were at risk of pulmonary disease(s).

“…However, these heavy metals can cause chronic adverse effects on the central nervous system, bones and all other organs; Within this group of metals, cadmium and lead are included, which are harmful to human health, even at low exposures (Martínez-Flores et al, 2013;Gómez-Marrugo et al, 2018). For these reasons, this project will determine heavy metals such as lead and cadmium in guava pulp (Psidium guajava) obtained in the city of Cartagena-Bolívar.…”

El objetivo de este estudio fue determinar los niveles de acumulación de metales pesados como el cadmio (Cd) y el plomo (Pb) derivados de actividades antropogénicas, como los humos metálicos de la soldadura y el tráfico de vehículos, en la pulpa de guayaba (Psidium guajava) en la ciudad de Cartagena. -Bolívar. Las muestras se dividieron en tres (3) grupos según la proximidad de las fuentes de contaminación. En el grupo 1, menos de 100 m de industrias metalúrgicas, las concentraciones de Cd en el rango de 0.0400 ± 0.33 mg / Kg y 0.0483 ± 0.15 mg / Kg, mientras que los valores de Pb oscilaron entre 0.036 ± 0.22 mg / kg y 0.060 ± 0.01 mg / kg . Para el grupo 2, se tomaron muestras en 3 lugares donde no se identificó claramente ninguna fuente de contaminación, lo que resultó en concentraciones de Cd 0.0215 ± 0.05 mg / Kg y 0.0260 ± 0.10 mg / Kg, mientras que para el Pb solo se encontró en una de las muestras cuyo valor fue 0.035 ± 0.15 mg / Kg. Finalmente, para el grupo 3, se tomaron muestras en 2 ubicaciones ubicadas a menos de 100 m de avenidas de alto tráfico, resultando en valores muy similares para Cd (0.0220 ± 0.13 mg / Kg y 0.0311 ± 0. 22 mg / Kg), mientras que para Pb el los valores fueron muy precisos (0.032 ± 0.35 mg / Kg y 0.029 ± 0.20 mg / Kg). Estas mediciones muestran cómo, en sitios cercanos a las actividades humanas, las concentraciones de estos metales pesados están en niveles más altos, lo que representa un peligro para su consumo debido a la bioacumulación en diferentes tejidos humanos.Palabras clave: metales pesados, humo metálico, contaminación, tráfico vehicular.
