Summary: Heavy metal pollution and hazards are major global concerns. A study in South China found that cadmium exposure exceeded national limits in PM2.5 and vegetables, mainly from industrial activities, with ingestion being the primary exposure pathway. Risk levels were found to be unacceptable, emphasizing the importance of multipathway and multimedia exposure assessment in health risk management.

Summary: The study found that gut microbiota plays an important role in the bioaccessibility of heavy metals in different age groups, with significant differences in metal exposure risks between adults and children. The bioaccessibility of heavy metals is primarily influenced by the total concentrations of metals in soils, followed by soil pH and active Fe/Mn oxide.

Summary: The pollution of heavy metals in soils of abandoned industrial sites in southeastern China is significant, posing risks to human health. Cd is the most susceptible to external factors, followed by Zn, Pb, Cr, Ni, and Cu. The bioaccessibility of heavy metals has a correlation with their bioavailability, and a regression model based on soil parameters can predict the bioaccessibility of heavy metals. The total concentration of heavy metals, Fe, soil texture, and pH control the bioaccessibility. The hazard index and carcinogenic risk values are significantly reduced when based on gastrointestinal bioaccessibility. This study provides a theoretical basis for the assessment of human health risks in abandoned industrial sites.

Summary: This study evaluated the risk to human health from consuming fruits, tubers, and fish contaminated with mercury and arsenic in a Colombian area affected by gold mining activities. The results showed that children and women of childbearing age had higher levels of methylmercury intake than the recommended safety limits. The intake of arsenic and mercury exceeded the safety levels for most population groups. There was also a potential risk of carcinogenicity from arsenic intake through food. Therefore, safety control mechanisms and environmental education strategies are crucial to protect the health of residents in areas impacted by gold mining activities.

Summary: The study assessed urban soil pollution by trace elements in China and found that 11% of cities are heavily polluted. Some cities exceed the standardly accepted tolerable levels of risk, with urban green spaces being threatened. It is recommended to alter the policy of urbanization and develop green infrastructures adapted to high contamination levels.

Summary: Using national multi-purpose regional geochemical survey data, this study systematically summarizes the pollution levels and health risks posed by 8 heavy metals in urban soils of 86 cities in the Yangtze River Economic Belt. The study found that Hg and Cd contamination in urban soils of the region is most prominent, while Cr and Ni contamination is almost nonexistent. The type of industrialization and urbanization history affect soil heavy metal pollution, and the influence of geological background cannot be ignored. The major pollutants in urban soils of Hunan and Hubei provinces are Cd, As, Pb, and Zn, while Hg pollution occurs in Zhejiang and Jiangsu provinces. The study also found that heavy metals generally pose low non-carcinogenic and carcinogenic risks to adults, but caution should be given to minors in certain cities.

Summary: Land application of municipal sewage sludge has become a popular option worldwide, but the heavy metals in the sludge pose potential ecological and human health risks. This study assessed the risks of heavy metals in sewage sludge samples from different cities in Turkey, finding that children may face higher health risks compared to adults due to exposure to Pb, As, and Cr. These findings suggest that regulatory limits alone may not be enough to protect all individuals from health risks associated with municipal sewage sludge.

Summary: This study assessed the contamination level and source of heavy metals in agricultural soil in central Shiquan County, revealing that chromium, copper, zinc, arsenic, lead, nickel, cadmium, and mercury exceeded their background values but not the risk control standards for agricultural soil pollution in China. The heavy metals in the soil were mainly derived from industrial pollution, except for lead which originated from soil parent material. The soil environment poses no non-carcinogenic effects on adults and children, but the high risk of cancer caused by chromium in local residents should be addressed.

Summary: This study found microplastic emissions in laundry water from household washing machines in Greater Kuala Lumpur, Malaysia, primarily in the form of fiber and fragment shapes such as polyester, nylon, and acrylic. The questionnaire survey indicated that fabric properties and washing parameters may contribute to microplastic emissions in laundry water at the household level. Further investigation is needed to understand the impact of fabric properties and washing parameter factors on microplastic emission in laundry water.

Summary: Rice is a staple food globally, but heavy metal contamination in rice production poses a significant threat to both the paddy ecosystem and human health. Cadmium, arsenic, and lead are identified as the most prevalent metals, with mining, irrigation, fertilizer, and pesticide usage being major sources. Health risk assessment through quantitative measurement is essential to identify potential risks from heavy metal exposure through rice consumption.

Summary: This study analyzes the presence and potential risks of microplastics in eight major bottled water brands in Malaysia. The results show that the concentration of microplastics in these bottled water samples is low, with particle sizes mainly ranging from 100 to 300 micrometers. Transparent microplastics are the most prevalent. The study finds that microplastics in bottled water mainly come from packaging materials and bottle caps. Although the estimated dietary intake values are low, the presence of plastic additives and residual monomers in these particles emphasizes the potential risks to human health.

Summary: The aim of this research is to investigate the occurrence, characteristics, and potential sources of microplastic pollution at four agricultural farms in Malaysia's tropical region of Klang Valley. The mean number of microplastic particles found in the agricultural soils were 2.1 +/- 0.44 to 3.4 +/- 1.2 particles/kg. Farms B and D had the lowest and highest total microplastic particle counts, 1.5 and 6.0 particles/kg, respectively, which was in line with the intensity of plastic consumption at these farms. These findings confirm the presence of microplastic pollution in Tropical agricultural soils and highlight the need to evaluate the negative impacts of long-term plastic use on agricultural soils.
