Dataset on total mercury (Hg) concentrations in soil, sediment, and fish from a recreationally impacted lake ecosystem (Gölcük Nature Park, Türkiye

This dataset contains total mercury (Hg) concentrations measured in surface soils, lake sediments, and fish tissues collected from Gölcük Nature Park (Bolu, Türkiye). Sampling was conducted during summer (July 2019) and winter (March 2020) to investigate seasonal variability and environmental distribution patterns. The dataset includes spatial coordinates, sample characteristics, and Hg concentrations (ng/g), supporting the analysis of Hg transport, accumulation, and environmental fate in a recreationally influenced ecosystem

本数据集收录了采自土耳其博卢省格尔居克自然公园（Gölcük Nature Park）的表层土壤、湖泊沉积物及鱼类组织中的总汞（total mercury, Hg）浓度实测数据。本次采样于2019年7月（夏季）与2020年3月（冬季）开展，旨在探究汞的季节变化特征与环境分布规律。数据集包含空间坐标、样品特性及汞浓度（单位：纳克每克，ng/g）相关数据，可为分析受旅游休闲活动影响的生态系统中汞的迁移、富集与环境归趋提供数据支撑。
