This research seeks to understand the publication types and ages cited most often in environmental health literature and the most commonly cited journal titles.
From the 43,896 items cited in Environmental Health Perspectives and the Journal of Environmental Health during 2008-2010, 2 random samples were drawn: First, 1,042 items representing all citations were analyzed with respect to publication type, age, and Internet link. Second, the cited journal name and citation age were recorded for 1,038 items culled from only citations to journal articles. All journal titles were classified into Bradford zones and assigned subject disciplines.
Journal articles (n = 891, 85.5%) were the most heavily cited publication type. Cited items' publication years ranged from 1951 to 2010. Close to half (49.1%) of all cited items were published 5 or fewer years previous. Sixteen journal titles (3.9%) accounted for 32.5% of all cited journal articles. The 3 most common subject disciplines-"Public, Environmental & Occupational Health," "Environmental Sciences," and "Toxicology"-accounted for 21.6% of all unique journal titles and 45.3% of all citations.
Environmental health citation patterns differ from other public health disciplines in terms of cited publication types, cited journals, and age of citations.
本研究旨在了解环境卫生文献中最常引用的出版物类型和年代，以及最常被引用的期刊名称。
从《环境卫生展望》和《环境卫生杂志》2008-2010 年引用的 43896 篇文章中，随机抽取了 2 个样本：首先，分析了 1042 篇文章，这些文章涉及出版物类型、年代和网络链接。其次，从仅引用期刊文章的 1038 篇文章的引用中记录了被引用的期刊名称和引用年代。所有期刊名称均被归入布拉德福区，并分配了主题学科。
期刊文章（n=891，85.5%）是被引用最多的出版物类型。引用文献的出版年份范围从 1951 年到 2010 年。将近一半（49.1%）的引用文献是在 5 年之前出版的。16 种期刊（3.9%）占所有被引用期刊文章的 32.5%。3 个最常见的主题学科——“公共、环境和职业健康”、“环境科学”和“毒理学”——占所有独特期刊名称的 21.6%和所有引用的 45.3%。
环境卫生的引文模式在引用的出版物类型、引用的期刊和引文年代方面与其他公共卫生学科有所不同。
