“…In a statewide analysis, Cushing et al found that, compared to areas with predominantly NL White residents, areas with larger populations of Latinx and POC (including African American, Native American, Asian/Pacific Islander, and or multiracial individuals) were associated with higher use of hazardous and volatile pesticides . In Ventura County, Temkin et al also found that toxic pesticides were disproportionately applied in communities with higher percentages of Latinx and POC populations . It is worth noting that these studies evaluated pesticide use in specific locations but did not consider PFAS-containing pesticide products specifically; however, we believe that similar underlying mechanisms, such as structural racism, are likely responsible.…”

Contaminated drinking water from widespread environmental pollutants such as perfluoroalkyl and polyfluoroalkyl substances (PFAS) poses a rising threat to public health. PFAS monitoring in groundwater is limited and fails to consider pesticides found to contain PFAS as a potential contamination source. Given previous findings on the disproportionate exposure of communities of Color to both pesticides and PFAS, we investigated disparities in PFAS-contaminated pesticide applications in California based on community-level sociodemographic characteristics. We utilized statewide pesticide application data from the California Department of Pesticide Regulation and recently reported concentrations of PFAS chemicals detected in eight pesticide products to calculate the areal density of PFAS applied within 1 km of individual community water systems’ (CWSs) supply wells. Spatial regression analyses suggest that statewide, CWSs that serve a greater proportion of Latinx and non-Latinx People of Color residents experience a greater areal density of PFAS applied and greater likelihood of PFAS application near their public supply wells. These results highlight agroecosystems as potentially important sources of PFAS in drinking water and identify areas that may be at risk of PFAS contamination and warrant additional PFAS monitoring and remediation.

“…The human toxicity potential (HTP) describes the potential for health damage from exposure to toxic chemicals, including carcinogens (HTPc) and noncarcinogens (HTPnc) [ 44 , 45 ]. In the agricultural sector, most emitted pollutants to the atmosphere are related to chemical fertilizers, pesticides, herbicides, and other agrochemicals, which play an essential role in human carcinogenic and noncarcinogenic toxicity [ 46 , 47 ]. The recent literature suggests that decreasing chemicals (fertilizers, herbicides, insecticides, and seed products) could be an effective technique for minimizing the human toxicity impact of wheat agriculture [ 48 , 49 ].…”

Wheat (Triticum aestivum L.) is a strategic agricultural crop that plays a significant role in maintaining national food security and sustainable economic development. Increasing technical performance considering lowering costs, energy, and environmental consequences are significant aims for wheat cultivation. For drylands, which cover approximately 41% of the world’s land surface, water stress has a considerable negative impact on crop output. The current study aimed to assess the environmental aspects of chemical fertilizer in combination with compost in dryland and irrigated winter wheat production systems through life cycle assessment (LCA). The cradle-to-farm gate was considered as the system boundary based on one tone of wheat yield and four strategies: D-C (dryland with compost), D (dryland without compost), I-C (irrigated with compost), and I (irrigated without compost). Based on the results, the highest and lowest amounts of wheat yield were related to the I-C and D strategies with 12.2 and 6.7 ton ha−1, respectively. The LCA result showed that the I strategy in comparison with other strategies had the highest negative impact on human health (49%), resources (59%), ecosystem quality (44%), and climate change (43%). However, the D-C strategy resulted in the lowest adverse effect of 6% on human health, 1% on resources, 10% on ecosystem quality, and 11% on climate change. Utilizing a combination of fertilizer and compost in dryland areas could ensure a higher yield of crops in addition to alleviating negative environmental indicators.
