Abstract:
... Research has demonstrated that intramuscularly embedded lead in humans and rats may cause direct plumbism, albeit rarely, and has identified risk factors to this end. To the authors' knowledge, this has not been investigated in wildlife, despite a high incidence of embedded lead in these animals secondary to cynegetic activities. Fourteen wildlife cases submitted to the National Fish and Wildlife ...

Subject:
algae; atrazine; environmental factors; geography; hydrochemistry; models; periphyton; phosphorus; phytoplankton; spring; streams; temporal variation; total suspended solids; Midwestern United States
Abstract:
... Potential effects of pesticides on stream algae occur alongside complex environmental influences; in situ studies examining these effects together are few, and have not typically controlled for collinearity of variables. We monitored the dynamics of periphyton, phytoplankton, and environmental factors including atrazine, and other water chemistry variables at 6 agricultural streams in the Midwest ...

agricultural runoff; atrazine; community structure; nutrients; periphyton; phytoplankton; risk assessment; seasonal variation; sediments; streams; summer; water quality; watersheds
Abstract:
... Numerous studies characterizing the potential effects of atrazine on algal assemblages have been conducted using micro- or mesocosms; however, few evaluations focused on in situ lotic algal communities, potentially confounding risk assessment conclusions. This exploratory study, conducted at several sites in the midwestern United States where atrazine is commonly used, presents in situ observation ...
