Behavioral Genetic Study

Aesthetic chills, broadly defined as a somatic marker of peak emotional-hedonic responses, are experienced by individuals across a variety of human cultures. Yet individuals vary widely in the propensity of feeling them. These individual differences have been studied in relation to demographics, personality, and neurobiological and physiological factors, but no study to date has explored the genetic etiological sources of variation. To partition genetic and environmental sources of variation in the propensity of feeling aesthetic chills, we fitted a biometrical genetic model to data from 14127 twins (from 8995 pairs), collected by the Netherlands Twin Register. Both genetic and unique environmental factors accounted for variance in aesthetic chills, with heritability estimated at .36 ([.33, .39] 95% CI). We found females more prone than males to report feeling aesthetic chills. However, a test for genotype x sex interaction did not show evidence that heritability differs between sexes. We thus show that the propensity of feeling aesthetic chills is not shaped by nurture alone, but it also reflects underlying genetic propensities.

Road traffic is a diffuse source of heavy metals and oil that leads to pollution of verges and surface water in areas immediately surrounding roads. The Commission for Integrated Water Management (CIW) has drawn up a policy document addressing methods for managing this type of pollution. The document is based on results from numerous studies in The Netherlands targeting pollution caused by traffic. The Commission concludes that measures at the source are the only way to realise sustainable solutions. For example, attention should be devoted to the issue of zinc emissions from car tyres and crash barriers. The concept of controlled infiltration is recommended for combating pollution caused by spray and runoff from roads. This includes periodic chemical inspection of verge pollution and, where necessary, replacement of the verge's top layer. The application of porous asphalt on highways in The Netherlands has also proven highly effective in limiting pollution caused by traffic, with far less pollution caused by spray from the highway and runoff as compared to traditional asphalt.

Fodder Production

A few decades ago in The Netherlands in the same way as in a number of other West-European countries a development started of excessive growth of animal husbandry. While in former agricultural production where animals were involved more or less a balance existed between the number of animals to be held on a certain farm, and the area available for feed and fodder production, this balance was now disturbed by the import of huge quantities of feed and raw materials for feed production. This has led to the situation that a mineral excess from animal manure exists for The Netherlands as a whole. In specific parts of the country, especially the sandy area, mineral availability has grown to excessive amounts. The environmental problems involved are related to:-leaching of nitrate to groundwater at a concentration level which causes unsuitability for drinking water purposes;-accumulation of phosphorus in the soil profile, and in case of P-saturation of the soil, leaching to groundwater and surface water, thus inducing eutrophlcation problems;-leaching of K to groundwater at a concentration level exceeding the potassium standard;-accumulation of heavy metals in soil, especially Cd, Cu and Zn, at a level which may induce malfunctioning of soil, both with respect to water quality, and to crop yield and crop composition.

Soil And Water

During incineration of municipal solid waste (MSW), various environmentally harmful elements and heavy metals are liberated either into bottom ash, or carried away with the off-gases and subsequently trapped in fly-ash. If these minor but harmful elements are not properly isolated and immobilized, it can lead to secondary environmental pollution to the air, soil and water. The stricter environmental regulations to be implemented in the near future in the Netherlands require a higher immobilization efficiency of the bottom ash treatment. In the present study, MSW incinerator bottom ash was vitrified at higher temperatures and the slag formed and metal recovered were examined. The behaviour of soluble elements that remain in the slag is evaluated by leaching extraction. The thermodynamics of slag and metal formation is discussed. The results obtained can provide a valuable route to treat the ashes from incinerators, and to make recycling and more efficient utilization of the bottom ash possible.

Thickness Measurements

The effect of external shipping traffic on the transport of polluted sediments into the inner city canals of Delft was investigated in a field study, measuring flow velocities and suspended solids contents in the water prior to, during and directly after passage of commercial vessels on the main navigation canal bordering the inner city canal system. Turbulent conditions caused strongly increased flow rates, viz. up to 1 m/sec. These flows were dominantly directed inwards, thus causing a net accumulation of pollutant-loaded sediment material inside the Delft inner city canals. Mass budget calculations as well as sludge thickness measurements revealed that of the ca. 520 tons of sludge material imported annually, about 40% can be attributed to external shipping traffic. The above observations were further supported in experiments with sediment traps located at stations within, as well as outside, the influence of the external shipping traffic. Here, also an apparent import of heavy metals (Pb, Zn, Cu), attached to the sludge material, could be observed.
