  1. Targeted Method for Quantifying Air-Borne Pesticide Residues from Conventional Seed Coat Treatments to Better Assess Exposure Risk During Maize Planting

    • Wed, 11/02/2022 - 04:00
    • Bulletin of Environmental Contamination and Toxicology
    • Agricultural seed-coat treatments are prone to drift as seed coatings may scuff off and become incorporated into field particles during planting. Vacuum planters release exhaust and kick up field dust, laden with systemic pesticides that blow across the landscape, is taken up, and later expressed in the nectar and pollen of surrounding plants.

  5. Can Pesticides Dissolved in Runoff and Exposed to Maturing Rice (Oryza sativa) Plants be Transferred to Seeds?

    • Wed, 01/12/2022 - 22:17
    • Bulletin of Environmental Contamination and Toxicology
    • Agriculture’s global challenge to feed an estimated 7.7 billion people is further exacerbated by less available cropland for production and rapidly changing climate patterns. Pesticides are often utilized to minimize crop losses due to pest infestations; however, problems arise when these chemicals are transported off production acreage, either by storm or irrigation events, and into nearby water bodies.

  9. Glyphosate: A Review on the Current Environmental Impacts from a Brazilian Perspective

    • Fri, 06/18/2021 - 02:01
    • Bulletin of Environmental Contamination and Toxicology
    • The indiscriminate use of glyphosate is one of the main agricultural practices to combat weeds and grasses; however, its incorrect application increases soil and water contamination caused by the product. This situation is even more critical due to its great versatility for use in different cultivars and at lower prices, making it the most used pesticide in the world. Nevertheless, there is still a lack of in-depth studies regarding the damage that its use may cause.

    • Sat, 09/26/2020 - 02:04
    • Bulletin of Environmental Contamination and Toxicology
    • Halogenated compounds are one of the largest groups of environmental-hazardous chemicals. The removal of the halogen atom from the substrate is possible by the catalytic activity of a type of enzyme called dehalogenase. Hydrolytic dehalogenases are suggested to be a good biodegradation catalyst for halogenated compounds with potential bioremediation applications. Therefore, the identification of possible bacterial strains that produce dehalogenase is of great importance.
