Home environmental health risks and the pollution of indoor residential air are becoming increasingly recognized as sources of injury and exacerbation of illness, particularly in vulnerable populations such as pregnant women, infants, children, the elderly, and those living with a chronic medical condition or disability. Nurses play a key role in prevention, education, and screening activities for patients. Core environmental health knowledge is essential for all nurses regardless of setting or population of practice. This article provides a review of the literature of five common home environmental health risks: lead, carbon monoxide, radon, pesticides, and the broad chemical category of volatile organic compounds. Particular emphasis is placed on the review of articles that address low-dose exposures, such as those most commonly found in the residential environment. Current standards of practice regarding risk minimizations are discussed, and nationally recognized preventative action steps and environmental health resources are presented.

Until recently very little archaeology in Cusco has focused on pre-Inka periods. This article aims to mitigate this shortcoming by presenting the results of excavations and artifact analyses conducted between 2005 and 2009 at Yuthu, a Formative Period site (400-100 BC). We will (1) describe the architecture and archaeological features found in two sectors at Yuthu, emphasizing the stratigraphic order and absolute chronology of the principal contexts, and (2) present the results of analyses of pottery, stone tools, animal bones, and botanical remains. The villagers of Yuthu divided their settlement into domestic and ceremonial spaces. Furthermore, they were shepherds and farmers living within a regional political system that was part of an even wider trade network that extended into the jungle and into other parts of the Andean highlands. ; La época preinka de la región Cusco ha sido poco estudiada hasta ahora. El presente artículo pretende contribuir a mitigar esta carencia respecto del Periodo Formativo de esta parte del Perú. Se exponen los resultados de las excavaciones y estudios arqueológicos realizados entre 2005 y 2009 en Yuthu, un sitio del Periodo Formativo Tardío (400-100 a.C.). Se describen las construcciones arquitectónicas y rasgos arqueológicos encontrados en dos sectores, con énfasis en el orden estratigráfico y la cronología absoluta de los contextos principales, y se presentan análisis de cerámica, objetos líticos, restos de fauna y flora. El texto demuestra que los pobladores de Yuthu ya tenían una división entre el espacio doméstico y ceremonial dentro de su comunidad. Además, fueron pastores y agricultores situados dentro de un sistema político regional que participaba en redes de intercambios más amplias que se extendieron hasta la selva y llegaron a otras regiones altoandinas.
