Lyviken : -bedömning av dagvattenkvalitet

AbstractStormwater is defined as rain- and melted water. Ludvika kommun had little knowledgde about the stormwater that reaches a specific recipient Lyviken. Therefore they intended to do an research of the stormwater that leads down to Lyviken. The aim with this study was to assess the quality of the contents in the stormwater based on pH, conductivity, phosphorous, nitrogen, bacterias, oil and one sample that meassured the value of several methals. Since the population has increased for decades, the area of hard surfaces and asphalts areas also has increased. This can increase the Pollutions that finally ends up in the recipient.

Föroreningsspridning via ledningsgravar : en fältstudie på Köpmanholmens industriområde

Sewer trenches usually contain material with a higher hydraulic conductivity then the adjacent soil. Thus they can serve as paths of preferential flow in a polluted area. Wastewater from factories can also leak from wastewater pipes and pollute the soil in the sewer trenches.The purpose of this project was to investigate Pollutions in sewer trenches and in sewer pipes in the industrial area of Köpmanholmen, 20 km south of Örnsköldsvik in the north of Sweden. To make an estimation concerning the potential of transport of Pollutions in sewer trenches, hydrological calculations were performed.Leakage to any greater extent did not seem to be a problem in the area. This is the case both for the concrete and the wooden pipes that have served as factory wastewater pipes.

Use of dogs as odour detectors : a review of the scientific literture

A lot of various substances can be detected by dogs, as oestrous in cows, endangered species or non-biological substances like accelerants, narcotics, explosives, mines and Pollutions and biological substances like identity (suspects), cancer (breast, lung, colorectal and bladder cancer), human remains (cadaver), bacteria and mould in buildings. The dogs are trained using non-scientific methods and not much research in detection training exists. This is a review of different types of dog detection, with focus on new research..

Tungmetallers påverkan på bottenfaunans artsammansättning i sjön Tisken

The purpose of this study was to investigate how elevated levels of heavy metals affect the faunal species composition, abundance and species-diversity. The bentic macroinvertebrate fauna in the highly polluted lake Tisken was compared with the bentic macroinvertebrate fauna in the unpolluted lake Varpan. Mine wastes account for most of the metal that is discharged into Tisken. The hypotheses was that the heavy metal Pollutions in lake Tisken influenced the species composition, abundance and diversity of the macroinvertebrates. Twenty samples were taken in both sites.

Växtanvändning i krävande miljöer : en studie i sydvästra skåne

Vegetation is a much appreciated element in our outdoor environment that has many advantages as well for the climate as for people?s health. However in some types of environments vegetation may be problematic. Especially in urban areas with limited space, solid surfaces, Pollutions, and warm and dry climate. In these environments vegetations may have difficulty surviving and moreover it may have a negative impact on the environment around it.

Elanslutning av fartyg i hamn : en studie om förutsättningar och konsekvenser för Köpings och Västerås hamn

The purpose of this thesis is to investigate the possibilities for shore side electricity in the ports of Västerås and Köping. A technical solution to connect the vessels to the local grid is suggested and the investigation is also aiming at an understanding of how the environment is affected by the use of shore side electricity. Furthermore, the costs of shore side electricity are considered.The maximum power demand of a vessel visiting the ports today is relatively small, but the ships visiting the ports in the future might have a larger power demand. The suggested dimension for the system is 5 MW and the result shows that the shore side electricity requires the power distribution to the ports to be expanded. The most useful solution in the ports is to connect the ships with 12 kV from a connection box in a pit at the quay.The investigation of the costs shows that it is cheaper for the ships to use electricity compared to the marine fuel.

Handlingsplan för rening av dagvatten från hårt trafikerade gator i Örebro

The main purpose with the project has been to approximate the magnitude of the pollution transport from the actual road surfaces and to get an approximation of the possibility to collect the pollutants to reduce the load to the water and improve the water quality.The quantity of pollution transport from the most trafficated roads areas in Örebro city has been calculated. Roads whith a traffic exceeding 10 000 vehicle/day. The study has been done with the calculation tool StormTac. Through analysis of traffic loads and road surface, which together with a different kinds of parameters gives an approximation of the pollutant transport.The calculation has included some metals and other substances in the stormwater and has also included the present of suspended solids. Included the overall study, some smaller areas has also been calculated for the possibility to remove pollutants.The work also includes calculation for three different areas for stormwater treatment.

Mjölkureahalten som mått på vom-mikrobernas kväveförsörjning och kons miljöbelastning

The aim of this literature study was to analyze how milk urea concentration is working as a measure of the nitrogen supply to rumen microbes and indicator of the environmental load. Questions included in this literature study were how to improve the dairy cattle nitrogen efficiency and what correlations there are between milk urea, nitrogen efficiency and crude protein content in the feed. Effects on the reproduction from high ration protein content are also addressed. Dairy cattle are today fed with large proportions of protein which could lead to high expenditure of feed and environmental Pollutions. The nitrogen can be lost to the environment by different pathways; leaching, denitrification or by emission to the air.

Samspel mellan miljo?politik, innovation och teknikutveckling : Fallstudier om svenska avlopp, kylska?p och bilar

Within process or manufacturing industries, the production of goods and services or the products themselves may have negative side effects such as pollution. An important task for environmental policy is to control and limit these Pollutions, for example via regulatory measures. Although, the efficiency of such measures vary greatly between different industries and an increasingly important task for environmental policy is then to encourage companies to engage in environmentally motivated innovation. Governments can utilize other measures than regulation to indirectly decrease pollution. This thesis aims to analyze such activities and how it affects the innovativeness of wastewater treatment, refrigeration and automobile manufacturing industries.

Miljö i fokus - En studie av de bakomliggande drivkrafterna för den ökade miljömedvetenheten inom svensk kemiindustri

BACKGROUND & During the last century, the Swedish chemical industry has developedPROBLEM: considerably in regard to respecting the environment. Following various discharges and Pollutions during the first half of the 20th century, environmental concepts such as CSR, Responsible Care and REACH have developed in order to improve the situation. Today, environmental issues play a central role in the society, but what are the reasons behind this increased environmental commitment? PURPOSE & The purpose of this thesis paper is to study the driving forces behindDELIMITATIONS: the increased environmental awareness in companies. Is this mainly due to stricter legislations, or do factors like pressure from the general public, the industry or customers play a more vital role? Furthermore, do economic incentives exist, that make it interesting for companies to invest in environmental awareness? Since the chemical industry spans over a wide spectrum in regard to environmental issues, this paper will focus on a specific area of the industry.

Effektivisering av ekologisk dagvattenhantering i stadsmiljö

I Jönköping har problemet med översvämningar, erosion och materialtransport varit ett stort problem i Strömsbergsbäcken i Jönköpings kommun. Detta har tillviss del orsakats av ett ökat dagvattenutsläpp i bäcken, vilket skapar kraftigaflödestoppar då den ursprungliga fåran inte är ?dimensionerad? för den ökadevattenmängden. Syftet med arbetet är att effektivisera ekologisk dagvattenhantering i stadsmiljö med högt dagvattenutsläpp. Målet med arbetet är i sin tur att framställa underlag för hur ekologisk dagvattenhantering i stadsmiljö kan genomföras och att rapporten skall kunna ge värdefull kunskap till liknande sammanhang.

Arboga Mekaniska Verkstad : Förslag på saneringsåtgärder gällande gjuteriet och plåtverkstaden

The industrialization in Sweden has increased the large number of areas that have been contaminated with various types of pollution. One of those sites are the property Höjen 3:24 in Arboga where ?Arboga Mekaniska Verkstad? once been. The property wants to increase the use of the old former foundry building with the adjacent ?plate-workshop? and believe there are two options for the building: That the building either should be used as a warehouse/concert hall, or rebuilt into a cultural center. An environmental evaluation has shown that the levels of heavy metals are over the Swedish environmental protection agency guidelines of less sensitive land.
