Best practices for exposure model peer review - A SciPinion advisory panel report.

The extent and rigor of peer review that a model undergoes during and after development influences the confidence of users and managers in model predictions. A process for determining the breadth and depth of peer review of exposure models was developed with input from a panel of exposure-modeling experts. This included consideration of the tiers and types of models (e.

Weight of evidence analysis of the tumorigenic potential of 1,3-dichloropropene supports a threshold-based risk assessment.

1,3-Dichloropropene (1,3-D; CAS #542-75-6) is a fumigant used for preplant treatment of soil to control parasitic nematodes and manage soil borne diseases for numerous fruit, vegetable, field and tree and vine crops across diverse global agricultural areas. In the USA, 1,3-D has historically been classified by the U.S.

How Adolescents Use Social Media to Cope with Feelings of Loneliness and Anxiety During COVID-19 Lockdown.

Next to physical health problems and economic damage, the coronavirus disease 2019 (COVID-19) pandemic and associated lockdown measures taken by governments of many countries are expected to cause mental health problems. Especially for adolescents, who highly rely on social contacts with peers, the prolonged period of social isolation may have detrimental effects on their mental health. Based on the mood management theory, the current study examines if social media are beneficial for adolescents to cope with feelings of anxiety and loneliness during the quarantine.

Assessment of acetochlor use areas in the sahel region of Western Africa using geospatial methods.

The goal of this study was to determine the co-occurrence between acetochlor use on crops and potentially vulnerable soils in the Permanent Interstate Committee for Drought Control in the Sahel region of Western Africa. Acetochlor, a pre-emergence herbicide, is used primarily on row crops and has the potential to reach groundwater or surface water following a rain event shortly after application. Off-field transport is often determined by soil properties; therefore, soils within potential use areas were assessed and mapped to establish areas with soils vulnerable to leaching and/or runoff.

Groundwater monitoring for 1,3-dichloropropene in high fumigant use areas of North America and Europe.

Background: 1,3-Dichloropropene (1,3-D) is a soil fumigant used for the control of nematodes in high-value fruit, nut and vegetable crops globally. Extensive water monitoring efforts have been undertaken over the past four decades by public and private institutions, given the widespread agricultural use of 1,3-D, and environmental fate and metabolism data suggesting the potential for 1,3-D to leach into groundwater. The aim of this study is to review the results of groundwater monitoring studies for 1,3-D conducted in North America and the European Union (EU) since 1980.
