Assessment of heavy metal pollution on agricultural land in Chengdu city under different anthropogenic pressures based on APCS-MLR modelling
2024Yizhou Peng, Grigorieva Iya Yu · Ecological Indicators · China (Chengdu)
This study assessed heavy metal pollution in rural, urban-rural interface, and urban agricultural lands in Chengdu, China. It found varying degrees of heavy metal pollution across all areas, with arsenic (As) and cadmium (Cd) being the most severe pollutants. Concentrations of As and Cd in soil samples exceeded risk thresholds, and these elements showed high spatial variability, indicating significant anthropogenic influence. Pollution sources included livestock manure, natural sources, agricultural activities, and industrial activities in urban areas.

2023Rajat Kumar · Ecology Economy and Society–the INSEE Journal · India (Delhi)
This paper investigates the toxicity in river water in the Yamuna khadar floodplains in Delhi, India, caused by pesticides and fertilizers used in agriculture. The study examines how this toxicity is perceived, discursively constructed, and dealt with by differently located stakeholders. It finds that stakeholders in the Yamuna khadar do not experience pollution as a homogeneous community, nor do they all perceive themselves as suffering from or contributing to the toxicity in a similar way.

A study surveyed 38 railway gardeners to characterize urban and peri-urban agricultural production along railway tracks in the Mumbai Metropolitan Region. Irrigation water contained nutrients but also heavy metals such as lead, cadmium, and mercury, and pathogens like Escherichia coli. Heavy metal levels exceeded critical thresholds in surface soils for chromium, nickel, and strontium, and in produce for lead, cadmium, and strontium.

A study in Bangalore city, India, showed that urban consumers are at greater risk of purchasing fresh fruits with high levels of heavy metals beyond the legally permissible limits defined by the Indian Prevention of Food Adulteration Act, 1954. These national norms are less strict than international food safety standards.
