exposure to di(2-ethylhexyl)phthalate(DeHP)in the indoor environment has been linked with significant health risks for Chinese ***-phase DeHP concentrations in Chinese residences and kindergartens were estimated using a mass balance model based on the current baseline condition and control strategies(i.e.,increasing ventilation rate,reducing area of sources,using mechanical ventilation systems,and using portable air cleaners).The health benefits of each control strategy were quantified as the reduction in lifetime cancer risks(LCr)and burden of disease(BoD).In the current situation,the mean LCr and disability-adjusted life years(DALY)number attributable to indoor DeHP exposure for Chinese children were around 6.0×10^(−6) and 155 thousand,*** mean LCr and DALY might be reduced by 25%-54%and 16%-40%,respectively,by increasing air exchange rates by 100%,reducing the use of source materials by two-thirds or deploying commercial air cleaners in naturally ventilated ***,avoidable DALYs could result in a reduction of mean economic losses of 2.2-5.3 billion *** ventilation systems with filtration units may not be helpful for reducing children’s health ***-specific and tailor-made control measures are critical in lowering indoor exposure to DeHP to promote sustainable buildings and children’s health in China.

The Paleolithic sites in South China have caused controversy regarding human behaviors in response to the rapidly shifting environment of the late Pleistocene. However， chronometric and high-resolution proxies are absent from interpreting the paleoenvironmental evolution. Here we present the chronology， grain size parameters， and geochemical elements records from the Hejialing (HJL) site in South China to reveal the crucial aspects of environmental evolution， and human occupation. The geochemical record shows that during MIS 5e–5a， northern Hunan experienced the influence of summer monsoon and maintained a warm and humid climate. The laterite layer began to develop. During MIS 4， the climate transitioned to dry and cold state， leading to the attraction of hominins to the HJL area due to the abundant water and lithic raw material resources， resulting in their establishment of a short-term camp. The HJL site was primarily inhabited by hunter-gatherer societies within a forested environment. From MIS 4 to MIS 2， Hunan experienced a prolonged period of dry and cold climatic conditions， with a brief rainfall recovery occurring in late MIS 3. Diminished vegetation and resource availability compelled human populations to broaden their activities and undertake migrations. The HJL site was abandoned amid the arid phase of MIS 2. The HJL area gradually became buried beneath eolian dust deposition (eM1) from distant sources and riverine dust from nearby sources (eM2)， and the site was informed. In MIS 1， During MIS 1， the climate shifted to a warm and humid state， marking the emergence of early agricultural practices. As an essential part of South China， the environmental evolution process and diverse survival strategies employed by hominins in Hunan are vital for explaining how the paleoenvironment drove human occupation during the Late Pleistocene.
