Southern exposure

The southern exposure and large windows makes this a very hothouse / hot house.

PVC coated aluminum siding experienced severe peeling of surface coating. The majority of peeling occurred on southern exposure. HPLC analysis showed that in the peeling area there was from 6 to 7.9% phthalate plasticizer. In nonfailing areas, concentration of the plasticizer was from 8.7 to 14.3%... 

Fig. 1. Southern blot analysis of DNA showing (a) step 1, an agarose gel containing separated restriction fragments of DNA, denoted by (—), which is immersed in NaOH to denature the double-stranded stmcture of DNA, and then transferred by capillary flow to a nitrocellulose filter. In step 2, the bound DNA is allowed to hybridize to a labeled nucleic acid probe, and the unbound probe is washed off In step 3, the filter is placed into contact with x-ray film resulting in (b) bands of exposure on the film which are detected after development and correspond to regions where the restriction fragment is...

This cascading effect may have been best demonstrated from interdisciplinary research addressing the consequences of chronic oxidant air pollution exposure to the mixed conifer forests of the San Bernardino Mountains of Southern California. Miller et al. (76) reported that chronic exposure to oxidant air pollutants resulted in decreased photosynthetic capacity, premature... 

The vein-type deposits can be divided into two based on the metals produced precious (Au, Ag) and base metal (Pb, Zn, Ag, Mn, Cu, Fe) vein-types. There are two sub-types of the base metal vein-type deposits, the Cu-Pb-Zn sub-type and the Pb- Zn-Mn-Ag sub-type. Cu-Pb-Zn veins occur in southern part of the province. Large Pb-Zn-Mn-Ag veins and Au-Ag veins are distributed in northeastern part. In the northeastern part, Au-Ag vein-type deposits occur in marginal zones of the province, while the base metal-rich deposits (Pb-Zn-Mn veins and Kuroko deposits) in central zone (Fig. 1.149). The marginal zone is characterized by exposure of Quaternary volcanic rocks and Plio-Pleistocene volcanic rocks in which Au-Ag veins occur, whereas the central zone is by thick submarine volcanic rocks (Fig. 1.150), in which base metal-rich deposits (base metal veins and Kuroko deposits) occur (Fig. 1.150). Tertiary volcanic rocks, Quaternary volcanic rocks and faults are distributed, trending generally from NW to SE. Some Cu-Pb-Zn veins in southern part are hosted by basement rocks. On the other hand, Pb-Zn-Mn-Ag and Au-Ag veins occur in Tertiary and Quaternary volcanic rocks. 

A field operator exposure study was designed to accommodate the chemical properties and the use pattern involved in the treatment of potato crops for protection against the Colorado potato beetle. Fifteen farmworkers experienced in the use of tractor-drawn sprayers for application of crop protection materials to crops were selected. All were adult males. To avoid production of a large quantity of treated potato crop prior to registration of the product for sale, the trials were performed on stubble fields after harvest of winter wheat crops in a potato-growing area of southern Ontario. This allowed the use of typical farm spray equipment and a typical duration of exposure for a complete shift of work. 

Resistant species, such as southern armyworms, require injected doses up to 800 mg KCN/kg BW (332 mg HCN/kg BW) or diets of 3600 mg KCN/kg for 50% mortality (Brattsten et al. 1983), but data are scarce for other terrestrial invertebrates. Exposure to 8 mg HCN/L air inhibits respiration in the granary weevil (Sitophilus granarius) within 15 min and kills 50% in 4 h some weevils recover after cessation of 4-h exposure (Towill et al. 1978).

In the southern direction the Podzols are transferred into Podzoluvisols and Distric Phaerozems. These soils have less acidity and less pronounced migration of various elements. Accordingly, this determines the exposure pathways of pollutants, like heavy metals, in soil compartments of forest ecosystems. 

Asthma rates in children in Southern California are high and oxidant pollution levels are likewise high. It is important to determine the relationship between the two. It is also important to determine whether there are chronic pulmonary effects produced by either these oxidants and/or particulate pollution. Since children spend more time outdoors than adults and since they exercise more while outdoors, the added assault from increased ventilation may be of importance. The studies feature a comprehensive exposure assessment that has led to a better understanding of the relationship between exposure and effects. It is also important to identify sub-populations of children and adults who are more susceptible to air pollution-related respiratory effects if they exist. Altered susceptibility could be based on genetic or non-genetic mechanisms (nutritional status for example). Both the epidemiologic and chamber studies provide opportunities to examine issues of hypersusceptibility and to determine the reasons for it if it exists.
