{"product_id":"2940014394857","title":"Regression Model for Explaining and Predicting Concentrations of Dieldrin in Whole Fish from United States Streams","description":"A regression model was developed for estimating dieldrin\u003cbr\u003econcentrations in whole fish from United States streams using\u003cbr\u003ewatershed characteristics, including estimates of past agricultural\u003cbr\u003euse intensity. Dieldrin concentrations were measured\u003cbr\u003ein composite whole-fish samples collected at about 650 sites\u003cbr\u003enationwide during 1992–2001, as part of the U.S. Geological\u003cbr\u003eSurvey’s National Water-Quality Assessment Program.\u003cbr\u003eImportant explanatory variables in the model include (1) fish\u003cbr\u003elipid content; (2) the estimated historical agricultural use\u003cbr\u003eintensity of aldrin and dieldrin (which was calculated from\u003cbr\u003eregional application rates developed using U.S. Department\u003cbr\u003eof Agriculture data on pesticide use by farmers in 1966\u003cbr\u003eand harvested acreage from the 1964 and 1969 Census of\u003cbr\u003eAgriculture); (3) a weighted termite-urban score (which\u003cbr\u003erepresents past use for termite control and was developed\u003cbr\u003efrom estimates of urban land use in the basin, combined with\u003cbr\u003ethe national distribution of subterranean termite density); and\u003cbr\u003e(4) forested land in the basin (where past aldrin and dieldrin\u003cbr\u003euse was expected to be minimal).","brand":"The Delano Max Wealth Institute, LLC.","offers":[{"title":"Default Title","offer_id":47070597415152,"sku":"2940014394857","price":2.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/2940014394857_p0.jpg?v=1763607641","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/2940014394857","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
