3. Can DBP affect the environment? - GreenFacts
The environmental exposure assessment of DBP will be based on the expected releases of the substance during the following life cycle stages: I. Production II. Distribution (e.g. road transport) IIIa. Processing in polymers IIIb-1. Formulation in adhesives IIIb-2. Processing/use of adhesives IIIc-1. Formulation in printing inks IIIc-2.
DBP: 3. Can DBP affect the environment? - GreenFacts
DBP does not readily break down in water. It does break down in the presence of air but breakdown is much slower in sediment, deep soil and groundwater. In the atmosphere DBP is broken down by sunlight. Its half-life in the atmosphere is estimated at 1.8 days.
Temperature dependence of characteristics of organic
This study characterized the potential effects of elevated water temperature on source water quality and corresponding disinfection byproduct (DBP) formation. Results of laboratory simulations showed that although DBP formation increased with temperature, both the concentrations of dissolved organic carbon (DOC) and DBP formation decreased when water was incubated at higher temperatures (35
Phthalate Di-butyl phthalate - SlideShare
Dibutyl Phthalate (DBP) is used in a wide range of products for everyday use such as plastics, paints, inks and cosmetics. Its widespread use has raised some concerns on the safety of this compound.

X-Press Pearl: The 'toxic ship' that caused an environmental
The plastic can take between 500 to 1000 years to decompose and is likely to be carried by ocean currents to shores all around Sri Lanka and even to beaches hundreds of kilometres away from the
- How does DBP affect the environment?
- These results indicate that DBP contamination accelerates carbon metabolism, which makes more carbon in soil converted to CO 2 and methane, causing loss of soil carbon pool, while inhibiting carbon flux from the atmosphere to soil, exacerbating the greenhouse effect and negatively affecting the environment.
- What is the effect of DBP on soil microbial communities?
- The effect of DBP on soil microbial communities has been investigated by many researchers [, , ]. However, there have been few reports about the effect of this toxic pollutant on the soil-vegetable system, especially on plant microbial community (include the phyllospheric and endophytic bacterial communities).
- What are the effects of DBP on bacterial communities?
- Both plant and soil bacterial communities were significantly altered under DBP treatments. The phyla Actinobacteria, Proteobacteria, Firmicutes, and Bacteroidetes accounted for upwards of 90 and 99% percent of those communities in soils and vegetable samples, respectively (Fig. S4).
- What are DBP concentrations in vegetable greenhouses and agricultural soils?
- The DBP concentrations were detected in vegetable greenhouses and agricultural soils in the Shandong Peninsula, China, ranging from 0.02 to 15.72 mg kg −1 and ND (not detected) to 9.86 mg kg −1, respectively (Chai et al., 2014; Li et al., 2016).
- How do different DBP concentrations affect the bacterial community structure?
- The principal co-ordinates analysis (PCoA) (Fig. S5A) and dissimilarity tests (Table S5) showed that the bacterial community structures of soils were significantly different between different initial DBP concentrations and among different time points ( P < 0.05).
- How does dibutyl phthalate affect soil microbial community structure?
- High concentration, low temperature and moisture slowed DBP degradation. DBP produced a long-term disturbance of soil microbial community structure. Due to its widespread application and large-scale production, dibutyl phthalate (DBP) has become one of the most frequently identified phthalic acid esters (PAEs) in soils.
