Heliyon, Journal Year: 2024, Volume and Issue: 10(7), P. e28357 - e28357

Published: March 26, 2024

Heavy metal (HM) poisoning of agricultural soils poses a serious risk to plant life, human health, and the global food supply. When HM levels in get dangerous levels, it harms crop health yield. Chromium (Cr), arsenic (As), nickel (Ni), cadmium (Cd), lead (Pb), mercury (Hg), zinc (Zn), copper (Cu) are main heavy metals. The environment contains these metals varying degrees, such as soil, food, water, even air. These substances damage plants alter soil characteristics, which lowers Crop types, growing circumstances, elemental toxicity, developmental stage, physical chemical properties, presence bioavailability (HMs) solution some factors affecting amount toxicity crops. By interfering with normal structure function cellular components, HMs can impede various metabolic processes. Humans exposed numerous diseases by consuming affected products. Exposure certain harm kidneys, brain, intestines, lungs, liver, other organs body. This review assesses (1) contamination through different sources, like anthropogenic natural; (2) effect on microorganisms properties soil; (3) well production; (4) entering chain associated hazards health. Lastly, we identified research gaps suggested further study. If people want feel safe their surroundings, there needs be stringent regulation release into environment.

Spatial distribution and risk assessments due to the microplastics pollution in sediments of Karnaphuli River Estuary, Bangladesh

Scientific Reports, Journal Year: 2022, Volume and Issue: 12(1)

Published: May 20, 2022

Abstract Microplastics (MPs) have become an emerging global pollutant due to their widespread dispersion and potential threats marine ecosystems. However, studies on MPs in estuarine coastal ecosystems of Bangladesh are very limited. Here, we conducted the first study abundance, distribution, characteristics, risk assessment microplastics sediment Karnaphuli River estuary, Bangladesh. Microplastic particles were extracted from sediments 30 stations along estuary by density separation then enumerated characterized using a stereomicroscope Fourier Transform Infrared (FT-IR) spectroscopy. In collected number varied 22.29 59.5 items kg −1 dry weight. The mean abundance was higher downstream left banks whereas predominant shape, colour, size films (35%), white (19%), 1–5 mm (30.38%), respectively. Major polymer types polyethylene terephthalate, polystyrene, polyethylene, cellulose, nylon. found pose risks (low high) with highest occurring at one station near sewage outlet, according results analyses pollution index, index (H), contamination factors, load (PLI). single value PLI, clearly demonstrated that all sampling sites considerably polluted (PLI > 1). H values showed toxic polymers, even lower proportions, possess polymeric hazard scores vice versa. This investigation uncovered new insights status laying groundwork for future research control microplastic management.

Health Risk and Water Quality Assessment of Surface Water in an Urban River of Bangladesh

Sustainability, Journal Year: 2021, Volume and Issue: 13(12), P. 6832 - 6832

Published: June 17, 2021

Despite significant contributions to the national economy of Bangladesh, various urban developments, massive industrial and growing shipping activities are making water many rivers, including Karnaphuli River, extremely polluted. To find out pollution sources their possible health effects, 45 samples were collected from 15 sampling stations. Investigation six physicochemical parameters (pH, temperature, total dissolved solids, conductivity, salinity, turbidity) through in-situ measurements eight heavy metals (Cd, Cr, Cu, Fe, Mn, Ni, Pb, Zn) status using atomic absorption spectrophotometer (AAS) was carried in this research. Both exceeded World Health Organization (WHO)’s permeable threshold limit. The calculated hazard quotient (HQ) index (HI) ingestion values indicate non-carcinogenic risk both for adults children, but dermal exposure within safety Carcinogenic analysis revealed that Cd could cause a cancer those river long period. Spatial metal (MPI) results exhibit downstream is more polluted than upstream river. Overall, findings study imply threat human will also help undertake proper management strategies incorporate monitoring programs implementation measures protect health.

Anthropogenic pollution has become a major issue governing ecosystem and human health risks. The Hangzhou Bay Qiantang Estuary region are facing unusual perturbation due to rapid development along the embayment in recent decades. This study evaluated organic inorganic pollutants water, sediment, from muscles of higher trophic organisms (fish, crustacean, shellfish) during four different seasons (in 2018-2019) assess potential hazard status. Dissolved phosphate nitrogen were this area, which led severe eutrophication throughout period. Eutrophication signals coincided well with phytoplankton abundance, revels control nutrient enrichment on spatio-temporal distribution phytoplankton.

It also evaluated human health risk adult children due to directly contact with through ingestion dermal pathways. ranges metal concentration area were found descending order as: Cr (0.036–0.054; mean 0.045 ± 0.005) > As (0.012–0.036; 0.024 0.007) Cd (0.009–0.050; 0.018 0.012) Pb (0.007–0.014; 0.009 0.007). In most cases, concentrations Cr, Pb, surpassed guideline limits consumption. However, one-way ANOVA revealed that average selected ten sampling sites not significantly different at a 95% confidence level. Therefore, it assumed contamination might have been caused anthropogenic along natural phenomenon. contents greatly concerning both winter summer seasons hazard quotient (HQ) index (HI) investigated compounds acceptable limit (< 1). addition, attribution did overweigh carcinogenic (CR) range (10 –6 10 –4 ), adults are more susceptible than children.
