ISBN-13: 9780470046302

prescribed drugs and private care products—we cannot reside with no them. Can the surroundings live on with them?

Pharmaceutical and private care items (PPCPs) are more and more being famous as micropollutants. during this context, pharmaceutical items surround a various variety of gear used to regard numerous health problems, and private care items comprise daily goods corresponding to soaps, fragrances, cleansing brokers, disinfectants, and related items. Written for execs from diverse backgrounds, Pharma-Ecology bridges the data and language hole and significantly examines the problem of PPCP micropollutants and the way to top reduce their impression at the setting. geared up systematically, it:

  • Presents a number pharmaceutical compounds classified through mode of motion and customary utilization, showing the volumes (or variety of prescriptions) which are dispersed
  • Discusses the detection of PPCPs within the atmosphere utilizing instrumentation and bioassay thoughts, together with microarrays
  • Covers the occurrences of PPCPs in aquatic structures, sediments, soil, and aerial environments
  • Considers the patience and degradation of PPCPs within the setting, and hyperlinks pharmacokinetics/pharmacodynamics with the kinetics of PPCPs within the environment
  • Explores engineering and remedy suggestions that may reduce the impression of PPCPs within the environment
  • Includes various tables and figures that illustrate information

this can be an enlightening reference for engineers, toxicologists, ecologists, micro-biologists, and chemists all for pollutants and environmental research; policy-makers; pros in federal and kingdom regulatory corporations; and pharmaceutical pros. it's also an exceptional textual content for undergraduate and graduate scholars in similar fields.

New PDF release: Every Molecule Tells a Story

By Simon Cotton

ISBN-10: 1439807736

ISBN-13: 9781439807736

From cooking to drugs, from engineering to artwork, chemistry—the technological know-how of molecules—is everywhere.

A occasion of the molecules of chemistry, each Molecule Tells a narrative celebrates the molecules liable for the reports of way of life: the air we breathe; the water we drink; the chemical compounds that gasoline our dwelling; the steroids that provide us intercourse; the colors of the seasons; the medication that heal us; and the scented molecules that improve our vitamin and our encounters with one another. You can’t see them, yet you recognize that they're there.

Unveiling the buildings of toxic "natural" ingredients and precious man-made molecules, this ebook brushes away any preconceived notions approximately chemistry to illustrate why and the way molecules topic.

Lebensmittelchemisches Grundpraktikum A. Themenkreis „Wasser - download pdf or read online

By Björn-Darjusch Buchmann

ISBN-10: 3668230986

ISBN-13: 9783668230989

Praktikumsbericht / -arbeit aus dem Jahr 2015 im Fachbereich Chemie - Lebensmittelchemie, be aware: 2, , Sprache: Deutsch, summary: Der vorliegende Bericht zum Lebensmittelchemischen Grundpraktikum A widmet sich dem Themenkreis „Wasser und Fette“.

Wasser ist das am häufigsten vorkommende Molekül. Es stellt die Grundlage des Lebens dar. Der menschliche Körper besteht aus 60 bis 70 % aus Wasser. Es übernimmt dabei im Körper regulatorische Aufgaben wie die Steuerung des Wärmehaushalts. Daneben fungiert es als Lösungs- und Transportmittel für polare und ionisierte Verbindungen, ist Strukturbestandteil von Makromolekülen und dient als Substrat enzymatischer Reaktionen.
Wasser besteht aus zwei Wasserstoffatomen und einem Sauerstoffatom und bildet somit die Summenformel H2O. Aufgrund der dipolaren Struktur, bei der das Sauerstoffatom negativ und die Wasserstoffatome positiv geladen sind, bildet Wasser Cluster aus, die durch Wasserstoffbrückenbindungen stabilisiert werden. Aus dieser Eigenschaft resultieren die Anomalien des Wassers. Durch die Wechselwirkung der einzelnen Wassermoleküle durch Wasserstoffbrückenbindungen ergibt sich der hohe Siedepunkt, der enorm von dem Siedepunkt der Hydride der Hauptgruppe abweicht (Bsp. Schwefelwasserstoff: -61 °C).

Aus dem Inhalt:
- Bestimmung der Trockenmasse in Fleisch und Fleischerzeugnisse;
- Wasserbestimmung in Lebensmitteln nach KARL-FISCHER;
- Extraktion nach Säure-Aufschluss (Methode nach WEIBULL-STOLDT);
- Extraktion nach ammoniakalischen Aufschluss (Methode nach RÖSE-GOTTLIEB);
- Chemikalien und Entsorgung
