As part of the California Air Resources Board's ongoing laboratory quality control and method validation program, researchers conducted comparative measurements of PM/sub 10/ nitrate and sulfate concentrations to demonstrate the equivalency of analytical procedures used in different laboratories. Surprisingly, the nitrate values measured after the six to eight months interim averaged 86% lower than those previously reported. The sulfate values stayed the same. This paper examines this rapid loss of nitrate from the PM/sub 10/ filters and the problems associated with using this method of measuring atmospheric nitrate.

The potential effects of ozone formation which would result if the 1985 vehicle fleet were converted from gasoline to ethanol/gasoline blends were investigated using the EKMA approach. Changes in vehicular emissions were used to calculate changes in ambient HC reactivities and ambient levels of HC, NO/sub x/ and CO for a number of scenarios. Ozone formation was then modeled for each scenario. Effects on ozone formation were not significant unless the usage of ethanol/gasoline blends resulted in deterioration of the emissions control systems. Ambient NO/sub x/HC ratios were shown to have a significant effect on ozone formation.

A method for measuring total nonmethane organic compounds (NMOC) In the atmosphere has been refined to reduce measurement variability and evaluated for possible use In connection with the control of hydrocarbon emissions. The method, a simplification of the conventional gas chromatographlc (GC) speciation technique, uses cryogenic preconcentration and flame ionization detection but does not use a GC column. Tests to compare this simplified method to the GC speciation technique, using actual ambient air samples, were carried out. Test results showed that the sensitivity and precision of the simplified method approach those of the speciation technique. Other test results verified that the use of stainless steel sample canisters for collection and temporary storage of NMOC samples Is acceptable and contributes little additional variability to the method.

During 1984, the California Indoor Air Quality Program undertook two studies aimed at evaluating the feasibility of using passive monitors, in combination with a mail-out approach, to measure formaldehyde concentrations inside a large sample of private residences. A pilot study in 51 nonmanufactured dwellings preceded an indoor formaldehyde survey in more than 500 mobile homes from throughout California. In the mobile home study, 663 residences were included in the summer phase (July/August 1984) and 523 in the winter phase (February/March 1985). Four hundred and seventy-two of these mobile homes were monitored twice, once in both the summer and winter phases of the study. Each investigation was carried out entirely by mail, including solicitation of volunteers, placement and recovery of monitors, collection of data on occupant- and housing-characteristics, and communication of test results. Results of formaldehyde measurements in both manufactured and nonmanufactured dwellings are presented and the feasibility of monitoring indoor air quality by mail is discussed.

Laboratory and field experiments were performed to evaluate integrative measurement methods for atmospheric nitrates, sulphate and sulphur dioxide. Denuder tubes and several filter media were tested under laboratory and field conditions. Effects of sampling variables such as temperature and relative humidity, flow rates, concentration, loading capacity and artifacts due to NO, NO2 and SO2 were also evaluated. The integrative filter sampling method and the ion chromatographic analytical procedure gave a measurement precision (relative standard deviation) of ±11.5 percent for particulate NO3 − on Teflon and ±15.6 percent for gaseous HNO3 on nylon; for both these constituents, the detection limit was about 0.1 μ m−3.

The Hazardous and Solid Waste Amendments to the Resource Conservation and Recovery Act direct the Environmental Protection Agency to determine the available treatment technologies for a number of hazardous waste streams, including halogenated organics. If it is determined that existing technology and capacity is sufficient for the safe management of the designated halogenated organic wastes, these wastes will be prohibited from land disposal, effective July 8, 1987. This article summarizes the general characteristics and treatment alternatives for this waste category.

Atmospheric pollution may be causing reduced growth and increased mortality of trees in forests in Europe and North America. Acid rain and ozone are the two pollutants most frequently mentioned as causal agents in the forest decline problem. One plant-environment interface where atmospheric pollution may be having an impact is the symbiotic association between roots and soil fungi known as mycorrhizae. Mycorrhizae are essential for the survival and growth of most forest tree species in the natural environment. Mycorrhizal fungi can affect the nutrient uptake and translocation, water uptake, root morphology, carbon metabolism and disease resistance of the host plant. In specific instances, mycorrhizal infection has been observed to enhance tree growth increase seedling survival or protect plants from root disease. Therefore, sensitivity of the mycorrhizal association to atmospheric pollution could be harmful to forest trees and might influence the decline of forests.
