Watercress is a semi-aquatic plant that grows in f lowing shallow freshwater and is found across Europe, Asia, the Americas, the Caribbean, New Zealand and Australia. Watercress is placed within the Brassicaceae family together with several other important food crops including broccoli, kale, cabbage, and mustard. A significant amount of commercial aquatic watercress cultivation is…

Ventura County is arguably the most complex county with respect to agricultural water
We also discovered that both water source and crop questions needed to be simplified. We achieved this by only asking for water source rank and name, which could be used to search external data for total dissolved solids, water price, and percent of supplier revenue generated from selling water to agricultural consumers. We simplified the crop…
Eggs collected were transferred into larval rearing trays containing spring water where they hatched
Few other household or subject characteristics were significant predictors of personal endotoxin exposure in crude models and all were confounded by dog and cat ownership. Significant predictors of indoor endotoxin in final multivariate models only included flooding damage and lower education levels in mothers that were unexpectedly associated with lower endotoxin. Overall evidence, including a lack…
Legionella species are found naturally in warm and humid environments
Huang et al. applied principal component analysis to data from their study, which showed that controlled exposure to CAPS from the Chapel Hill area induced an increase in neutrophils in the bronchial and alveolar fraction and increased blood fibrinogen levels in young healthy adults . The results of this analysis indicated that among the water-soluble fraction of…
The major metabolites of PCBs are methyl sulfones and polychlorobiphenylols
TDI or acceptable daily intake values indicate the amount of a chemical a person can be exposed to on a daily basis over his or her lifetime without suffering deleterious effects. There are numerous indications from studies of adipose, serum, and breast milk levels showing that exposure to OCs has been generally declining in North…
Serum concentrations of phthalate ester metabolites allow more direct exposure assessment
Despite their lipophilic nature, phthalates are metabolized and excreted in feces and urine within 3 d; consequently, bio-accumulation is not believed to be a problem. Studies measuring urinary monoester metabolite concentrations have revealed higher and more widespread phthalate exposure than had previously been suspected . Notably, several studies have indicated that concentrations of most urinary phthalate…
The other model covariates aside from cannabis also varied by species
Deer and tree squirrel occupancy probability increased with distance from cannabis farms, indicating potential avoidance. Domestic dogs, as expected, decreased in predicted occupancy with distance to cannabis farms. Interestingly, gray fox and ground squirrel occupancy probability also decreased with distance from cannabis farms, indicating that these species may be more likely to be found on…
Many also expressed concerns about ecological damage from the cannabis industry
Cannabis was located on average 273 m closer to coho salmon habitat than private parcels overall, 387 m closer to fall run chinook, and 132 m closer to winter run steel head, though the IQR intervals overlap. This proximity to freshwater in Josephine County was also generally closer than observed in other legacy cannabis regions .…
