检测

Indoor environmental quality assessment

This assessment is our most common service which aims to identify whether there are any indoor environmental quality issues in the occupied space. We not only offer a comprehensive test panel sampling for common indoor pollutants, but also conduct a walkthrough to identify areas of concerns and how to mitigate them.

Reasons to conduct this type of assessment include gauging the environmental quality of a new renovation, regulatory compliance with national (GB50325-2010, GB/T18883-2002) and international standard (EPA, OSHA, etc.), and help identify what may be leading to staff discomfort and/or complaints.

Common contaminants tested include:

  • air–PM2.5, formaldehyde, TVOC, lead, benzene, radon, ammonia
  • water–chlorine, lead, colony count, nitrates, heavy metals, etc.
Leakage

PM 2.5 and building tightness investigation

In China, PM2.5 pollution is an unavoidable topic of concern. 

This investigation audits a building’s envelope tightness, HVAC system, recirculating filtration, and occupant activities to ultimately determine how much protection the building is providing from outdoor particulate pollution. We also measure carbon dioxide levels to determine whether a tight space is providing sufficient fresh air for the occupied space.

Using a combination of handheld instruments and continuous monitors, we can identify leaky windows and doorways, saturated filters and purifiers, indoor sources of dust, and the space’s PM2.5 action level––the outdoor PM2.5 level at which the interior environment is projected to surpass standards.

Mold investigation and testing

PureLiving is the only environmental consultancy in China that provides mold testing, investigation, and remediation services in accordance to international best practices.

Mold

Mold testing

Mold testing helps identify whether there is a mold issue and is particular useful in cases where there are no signs of visible mold growth but odors, occupant symptoms, and/or moisture issues suggest otherwise. Mold samples are collected in the areas of concern and shipped to the US for analysis. Results determine:

1)  the severity of mold growth by comparing measurements against outdoor reference and indoor control levels and

2)   the types of molds colonizing the area and whether they are harmful to humans (i.e. Stachybotrys Chartarum AKA “Toxic Black Mold”).

Mold

Mold investigations

Mold requires oxygen, a food source (typically cellulose-based materials), the right temperature, and moisture to proliferate. The goal of a mold investigation is to identify how to limit moisture, as it is almost always the easiest factor to control.

PureLiving consultants utilize a combination of hygrometers, thermal imagery, moisture meters, bore scopes, and experience to identify the source of moisture then provide written step-by-step directions on how to stop the mold source and how to physically remove the growth.

Chemical

Chemical and odor investigation

This investigation has two purposes:

1)identify an unknown odor

2)determine what chemical is leading to elevated TVOC levels after conducting an indoor environmental quality assessment.

We do this by utilizing an advanced TVOC analysis method––which can identify over 65 different VOCs in the ambient air as opposed to a single cumulative concentration that is usually derived––then comparing the results with odor thresholds and reference standards to determine what chemicals occupants may be sensing. We also use an imported real-time TVOC sensor that allows us to “bloodhound” and identify indoor sources of chemical emissions.

Lead investigation

Lead and asbestos investigation

Lead and Asbestos are materials known to cause cancer.

However, they are loosely regulated and still commonly found in construction materials and older buildings. This testing aims to identify whether there is lead or asbestos in the airway, water, or building materials.

LEED

LEED (V2009 and V4) and WELL consultation and testing

LEED and WELL projects can get complex and overwhelming.

We help clients achieve the air and water concepts requirements by determining the most practical features for a project space and designing and implementing strategies to accomplish the said features. We provide diagnostic air testing with real-time instruments to give instant results and also design filtration solutions to ensure the project space complies with LEED and WELL’s stringent air quality requirements.

In additional, we have successfully completed Asia’s first Indoor Air Quality Assessment credit testing for LEED v4 and can offer this service for LEED projects.

re-stacking

Office re-stacking projects

Office re-stacking projects need to juggle not only the complexities of a typical renovation but also take into consideration how to limit renovation pollutants contaminating the occupied workspace. This type of project utilizes a variety of our services to ensure that emissions created during renovation do not enter the occupied workspace.

过滤

颗粒物和烟雾过滤

境纯的Pure-Qi天花板安装式空气净化器是模块化、高度可定制的单向过滤系统,预装有聚丙烯微粒过滤介质,能够去除98%以上的颗粒物质,包括烟雾、PM2.5和微生物。

化学还原

甲醛、气味和化学还原

Pure-Qi净化器还可选配我们专有的多功能高效催化清洁(MHCC)钾浸碳介质,现已证明,能够在一小时内去除99%以上的甲醛和98%以上的总化学污染物(TVOC)。

同时,对于化学气体污染特别严重的区域,境纯提供光触媒(PCO)治理,通常可以立即降低40%--90%的污染物。光触媒技术利用化学物(通常为二氧化钛),将其喷洒于家具、墙壁和地板等物体表面,用于处理室内较高的VOC和气味水平。喷洒的二氧化钛能够降解空气中的氮氧化物、甲醛、苯等挥发性有机化合物(VOCs)。被喷洒的物体表面就成为了治理区域。当紫外线照射时,二氧化钛就变成了光催化氧化剂(PCO)。碳氧键(形成大多数的有机化合物、细菌的结构)在TiO2的催化氧化作用下产生光化学反应而断裂,经过一轮一轮的作用下,最终只留下CO2和水(安全物质)。治理过后留下的二氧化钛层的保护作用并没有结束,它将持续抑制气体的释放同时抗菌。这个保护层即不会损坏物体表面,也不会改变家具和织物的纹理。氧化过程最好有光(人工或自然光均可),在黑暗中也能发生反应(有效性约为30-50%)。

Mold Removal 

In China, it is a common occurrence for maintenance teams and landlords to overlook the severity of mold issues and simply paint over visible growth.  This “Band-aid” solution is deceptive and potentially dangerous because contaminants are still present in the occupied space and can exacerbate or lead to the development of allergies.  PureLiving provides end-to-end mold removal service in accordance with the ANSI/IICRC S520 Professional Mold Remediation Standard. 

We incorporate a combination of products, services, and techniques to:

1) stop the source of moisture leading to perpetual mold growth and

2) physically remove mold spores and structures to limit occupant exposure and thus adverse health effects.
