Book excerpt: Excerpt from Major, Minor, and Trace Elements of Bottom Sediments in Lake Du Quoin, Johnston City Lake, and Little Grassy Lake in Southern Illinois Bottom sediments from three Southern abstract Illinois lakes, Lake duquoin, Johnston City Lake, and Little Grassy Lake, were analyzed chemically for eleven major and minor constituents - Si02, A1203, Kzo, C30, Mgo, Fe203, Tiog, mno, P205, coz, and total carbon; and ten trace elements-b, Cu, Co, Ni, Be, Cr, V, Zn, Sr, and Zr. The less-than-two micrometer clay-size fraction was determined by the pipet method. The sediments from Lake Du Quoin and Johnston City Lake have a high clay content in the upper portions of the bottom sediment cores and a low clay content in the lower portions with a definite transition point demonstrated in twelve of fourteen cores. Above this transition point, copper and zinc have maximum concentrations of 476 and 252 ppm, respectively, in Lake Du Quoin and maximum concentrations of 238 and 259 ppm, respectively, in Johnston City lake sediments. Copper and zinc have been contributed from external sources. The lower portions of the cores from these two lakes and the entire cores from Little Grassy Lake are chemically similar to sediment samples from ancient (wisconsinan and Holocene) Lake Saline.
