In this paper, we examined the response of geochemical records in lacustrine sediments to climate and human activity in Mengjin, Henan Province of China during the middle Holocene. Indices used in this study include K, Na, Mn, Ba, Sr, Al, Ti, cation ratios, and Gramineae pollen in lacustrine sediments. Results indicate a drought event in this area around 5660 cal a BP, which weakened soil leaching and changed the element composition of surface soil runoff entering the paelo-lake and lacustrine sediments. Human activity appearing from 4695 cal a BP to 4000 cal a BP also affected the chemical composition of lake sediments. Human activities led to enhanced soil erosion and destroyed soil leaching horizons. Therefore, the substance of soil illuvial layer exposed to the surface and entering the paleo-lake were substantially altered by human activities.

“…Together, these studies build up an accurate record of the industrial history and the environmental consequences for a large area of central Sweden. Across the Baltic in Estonia, the legacy of oil shale mining and power generation in terms of heavy metal fluxes was assessed by Punning et al (1997), distinguishing direct pollution effects and indirect disturbance of the hydrology.…”

Since the first studies reporting recent stratigraphic changes of metal concentration in lake sediments, many hundreds of studies have been published in the peer-reviewed literature. It is an impossible task to do justice to all of these works here; instead we: (1) examine recent methodological advances and place these in the context of the historical development of the discipline; and (2) explore the various purposes to which such methods have been applied. Such a historical emphasis may appear in conflict with the needs of a review of new approaches; however, this is not in fact the case for two main reasons. First, most new advances supplement rather than replace traditional methods, such that a thorough understanding of the practical and theoretical issues impacting these is still essential for reliable interpretation of palaeolimnological data. Second, while many of the new methods purport to circumvent problems, they achieve this only under favourable conditions, not dissimilar to the conditions that influence the earlier methods, so the same lesson must be learned anyway. Consequently, we use this historical narrative to address the fundamentals of the discipline.The chapter comprises two main parts; methodology and applications. The methodological section has three subsections: (1) Introduction to processes controlling natural variations in metal fluxes and concentrations in lake sediments; (2) Measurement of metal concentrations in sediments; (3) Calculation of enrichment or fluxes from sediment metal concentration data.There are four main applications subsections focusing on the value of lake sediment records of metals derived from mining or industry. They are: (1) Geochronological markers in sediments providing chronology for other research goals; (2) Lake sediment heavy metal records to quantify pollution loading histories, or to
