TL;DR: The similar Pb isotopic signatures of the sediments offered strong evidence that the PRE was a major source of trace metals to the adjacent coastal area, and slightly lower Pb/Pb ratios in the coastal sediments may indicate other inputs of Pb in addition to the PRE sources, including the inputs from Hong Kong and other parts of the region.

TL;DR: In this paper, 21 core samples (up to 3.65 m deep) were collected in the Pearl River estuary and about 15 subsamples from each core were analyzed for moisture content, total organic matter (L.O.I), particle size and heavy metal and major element concentrations.

TL;DR: The chemical forms of heavy metals in sediment cores of the Pearl River Estuary were studied using a sequential chemical extraction method and the 206Pb/207Pb ratios in the exchangeable fraction were the lowest among the five fractions, particularly in top sediments, showing the anthropogenic inputs ofheavy metals from recent rapid industrial development in the surrounding region.

TL;DR: In this article, the authors investigated the nature of emission sources and their relative contributions to ambient concentrations of volatile organic compounds (VOCs) and carbon monoxide (CO) at a rural site in eastern China.

TL;DR: In this article, the authors analyzed 16-month data of 13 major halocarbons measured at a southern China coastal site in the greater Pearl River Delta (PRD) from August 2001 to December 2002.
