“…With rising water scarcity and increasing water pollution, the U.S. Environmental Protection Agency and state and local regulatory agencies are limiting groundwater withdrawals for agriculture and, in some cases, mandating runoff capture and reuse (Beeson et al, 2004;Fulcher et al, 2016). Moreover, regulations aimed at reducing fertilizer and pesticide runoff will likely increase (Lin et al, 2009). With this changing scenario, the nursery industry is obliged to consume less fresh water (Fulcher et al, 2016) and find ways to capture and reuse nursery runoff.…”

Interest in capturing and reusing runoff from irrigation and rainfall in container nurseries is increasing due to water scarcity and water use regulations. However, grower concerns related to contaminants in runoff water and other issues related to water safety are potential barriers to the adoption of water capture and reuse technologies. In this review, we discuss some of the key concerns associated with potential phytotoxicity from irrigating container nursery crops with recycled runoff. The concentration of pesticides in runoff water and retention ponds is orders of magnitude lower than that of typical crop application rates; therefore, the risk of pesticide phytotoxicity from irrigation with runoff water is relatively low. Nonetheless, some pesticides, particularly certain herbicides and insecticides, can potentially affect crops due to prolonged chronic exposure. Pesticides with high solubility, low organic adsorption coefficients, and long persistence have the greatest potential for crop impact because they are the most likely to be transported with runoff from container pads. The potential impact on plant growth or disruption of physiological processes differs among pesticides and sensitivity of individual crop plants. Growers can reduce risks associated with residual pesticides in recycled irrigation water by adopting best management practices (e.g., managing irrigation to reduce pesticide runoff, reducing pots spacing during pesticide application, use of vegetative filter strips) that reduce the contaminant load reaching containment basins as well as adopting remediation strategies that can reduce pesticide concentrations in recycled water.

“…The Ro/La‐RNP complex possibly also includes the proteins calreticulin and nucleolin . The association of Ro60 with Y‐RNAs, small RNAs of 80‐112 nucleotides of unknown function, is found in both animal and bacterial species . The binding of Y‐RNAs is known to regulate Ro60's subcellular distribution from primarily cytosolic to nuclear, while also inhibiting access of other RNAs to binding sites in the protein's central cavity .…”

One of the major targets of the autoimmune response in the rheumatic autoimmune diseases, Systemic Lupus Erythematosus and Sjögrens Syndrome, is the protein Ro60. Ro60 is known to associate with small misfolded RNAs, and is involved in RNA quality control and in enhancing cell survival during cellular stress, e.g. after ultaviolet irradiation. In this study, six monoclonal antibodies to Ro60 were analyzed in order to identify antigenic regions and the nature of these. Preliminary analyses revealed that two of the antibodies recognized continuous epitopes, while the remaining antibodies most likely recognized conformational epitopes. The continuous epitopes of Ro60 were characterised by modified immunoassays employing resin-bound peptides and free peptides. Peptide screenings located the epitopes to the N-terminus of Ro60, and further analyses indicated that the epitopes of the monoclonal antibodies TROVE2 and SSI-HYB 358-02 were located to amino acids 8-17 and 34-49, respectively. Moreover, charged amino acids were found to be especially important for antibody reactivity, although antibody reactivity of the monoclonal antibody TROVE2 primarily was found to be epitope backbone-dependent.

“…This type of pollution is defined as "pollution coming from diverse diffuse sources including urban storm water, agriculture, and hydromodification, etc." (Lin, et al, 2009). Urban watersheds are also contributing to nonpoint pollution and causing water quality hazards of surface waterbodies (Lin, et al, 2009).…”

Nonpoint Source Pollution

Abstract: A critical review of the peer‐reviewed literature published in 2008 on topics related to nonpoint source pollution (NPS) is presented. This review is divided into three sections: sources of NPS pollution, modeling of NPS pollution, and NPS control strategies.
