“…There is a wide variety of commercially available burlap materials, and some contain toxic chemicals. Burlap used for produce or live plants is typically treated to inhibit microbial development (Bashkin 2003), while burlap from fabric stores is often coated with a number of chemicals to provide desirable qualities, such as resistance to stains, moisture, flame, and odor (Franke et al 1994). Unfortunately, information on chemical applications to the fabric was not available at the retail level for the burlap used in this study.…”

The freshwater oligochaete Lumbriculus variegatus is tank cultured to provide organisms for aquatic habitat assessments and regeneration research and to produce a clean source of live food for aquarium fishes. Shredded paper is the typical substrate in small-scale culture of L. variegatus. However, the effort needed to separate large numbers of individuals from decomposing paper can be prohibitive. Burlap and nylon mesh materials were compared with paper as potential alternatives for reducing this effort. Production and the time needed to separate L. variegatus from substrate were compared for 8 weeks among cultures with burlap, mesh, and paper substrates. Cultures with paper increased in number and weight faster than those with burlap or mesh, but cultures using the alternative substrates also expanded their populations quickly. The time required to separate oligochaetes from substrate was initially longer with paper and became significantly longer at 6 weeks as the paper decomposed. Burlap frayed, but mesh exhibited no degradation. Elevated ammonia and nitrite concentrations may have suppressed production in mesh treatments throughout the study, and ammonia was lethal in paper treatments during the final 2 weeks. Slow initial production in burlap treatments may have been due to chemical applications to the fabric, which may limit the utility of burlap as a substrate. Culture systems that maintain adequate water quality could increase production from burlap and mesh substrates to levels observed with paper substrate. Mesh is recommended because it is nontoxic and nonbiodegradable and can significantly reduce the effort required to obtain oligochaetes and to maintain and monitor the cultures.Lumbriculus variegatus is a ubiquitous freshwater oligochaete that lives in shallow lentic sediments and is a primary food organism in freshwater food webs. This species is used for aquatic habitat assessments, evaluations of aquatic contaminant bioaccumulation, and studies examining the physiology of regeneration processes, and it is also used as a source of live food for cultured fish (Drewes and

“…For the RTI/EPA study, it was necessary to develop and test a method to collect dust for microbiological analyses (Leese et al, 1993). The HVS3 has been used elsewhere for biological sampling (Gyntelberg et al, 1994). For each monthly monitoring, one sample per floor was taken of carpeted area, either a single area or a composite.…”

Cleaning for Improved Indoor Air Quality: an Initial Assessment of Effectiveness

et al. 1997

A study was conducted to characterize the indoor environment of a multifloor, multiuse, nonproblem, noncompliant building through long‐term monitoring for biological, chemical, and particulate pollutants. The study also assessed the effects of cleaning on indoor air quality by providing a program to monitor baseline levels, providing a rigorous (deep) cleaning of the building, and then continuing to monitor after implementation of a standardized, improved, cleaning program. To assess the effectiveness of the cleaning program, air, surface, and dust data from monitoring prior to the cleaning program were compared with those obtained while the improved housekeeping program was in place. Correlations between pollutants and other environmental factors were studied. The data suggest that the improved cleaning program contributed to indoor air quality through the reduction of airborne dust mass, total volatile organic compounds, and culturable bacteria and fungi.
