TL;DR: The 2019 dissolved reactive P (DRP) load from March-July was 29% lower than predicted, while the particulate P (PP) load was similar to the predicted value, resulting in a less severe HAB than predicted based on discharge volume.

TL;DR: For Lake Erie, it is already time to revise the phosphorus target loads set to address the problem of cyanobacterial blooms in the Western Basin by the Annex 4 task group in 2015, adopted by U.S. and Canadian governments in 2016 and set as objectives of domestic action plans in 2017 as discussed by the authors.

TL;DR: Ass assessments of human exposures to atrazine though drinking water have been carried out for the populations of the states of Ohio, Illinois, and Iowa and indicate that atrazines exposure through drinking water does not represent a significant human health threat based on the current understanding of atrazin toxicity.

TL;DR: In this paper, the authors used the Beale Ratio Estimator to calculate the load of the herbicides atrazine, alachlor, cyanazine, metolachlor and metribuzin for the period 1983-1993.

TL;DR: The results show that phosphorus removal programs are having the predicted effect on Lake Erie water quality as mentioned in this paper, and the effect of the phosphorus reductions can be seen in the lake concentrations and were predicted by a three-basin phosphorus budget model developed in the early 1970s.
